| Abstract: | This work describes the characteristics of a tsunami with an initial negative wave in the Pacific Ocean. These tsunamis fall into two classes; one class is produced by strong earthquakes and the other by earthquakes of moderate size. The relationship between the run-up probability occurrence is determined for both classes of tsunami and the mechanisms by which the tsunamis are generated is considered with reference to the keyboard model of tsunamigenic earthquakes. Tsunamis in the Arica region of northern Chile were analysed in more detail and these analyses suggest that a catastrophic tsunami is likely to occur in the Arica region in the next 10–20 years. |
